Abstract

PURPOSE:To enhance watertightness with a seal material and alleviate a work at a site by preliminarily containing the seal material in an elastic joint filler and applying an watertight effect only with the elastic deformation of the filler material proper via the elastic insertion of the filler material into a filler groove. CONSTITUTION:An upper layer fin-shaped part 7, an elastic fin piece 8 and a seal material retaining part 13 are provided on a joint filler A made of rubber or a rubber-like elastic body via an extrusion forming process. A recess 3 is formed within the retaining part 13 and a seal material 4 like a paste is filled therein, while an overflow passage 5 is formed. Furthermore, when the joint filler A is pushed into a filler groove 1, the seal material 4 is forced to overflow due to the elastic deformation of the retaining material 13, thereby filling a cavity in the filler groove 1. According to the aforesaid construction, a work for filing the seal material 4 at a site can be eliminated, and good watertightness can be obtained with the seal material 4, in addition to watertightness available from the fin-shaped part 7 and the fin piece 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a watertight joint material that is inserted into a joint groove, and more specifically, to attach a joint main body using a sealing material while removing a troublesome seal. This relates to technology that attempts to eliminate the work of filling materials.

[Jumei technology] As shown in Fig. 3, for example, a joint material A' is loaded into the joint groove 1 between the outer walls 6 and 6 to seal the joint groove 1 and maintain the appearance of the joint. be.

[Problem to be Solved by the Invention 1] By the way, the joint material A' is made of a rubber material and is elastically deformed and inserted into the joint groove 1, but when the side end surface of the outer wall 6 has large irregularities, However, there was a problem in that the joint material A' could not follow the irregularities, creating gaps, allowing rainwater to infiltrate through these gaps, and preventing the infiltrated rainwater from draining out, impairing watertightness.

To solve this problem, it is possible to fill the sealing material, but the sealing material protrudes from the joint groove 1, deteriorating the appearance. There was a problem that the filling operation was troublesome.

The present invention was made in view of such problems,
The purpose is to provide a watertight joint material that uses a sealing material to ensure reliable watertightness, but also eliminates the troublesome filling operation of the sealing material.

[Means for Solving the Problems] The watertight joint material of the present invention has a width W approximately equal to the width of the joint groove 1 and has a recess 3 formed at the back of a joint main body 2 that can be elastically deformed. The recess 3 is filled with a sealing material 4 that does not flow out when no external force is applied to the recess 3, and an overflow channel 5 is provided in the recess 3 to allow the sealing material 4 to overflow from the recess 3 to the outside by elastic deformation due to the external force. It is characterized by being formed.

[Operation l] In this way, a recess 3 is formed at the back of the joint main body 2 which can be elastically deformed, and the sealing material 4 that does not flow out in the natural state where no external force is applied to the recess 3 is filled and retained. This eliminates the filling work of filling the sealing material 4 into the recess 3 in advance and filling the joint groove 1 with the sealing material 4 at the construction site, and avoids troubles caused by insufficient filling of the sealing material 4. By forming an overflow path 5 in the recess 3 that allows the sealing material 4 to overflow from the recess 3 to the outside by elastic deformation due to external force, the recess is caused by elastic deformation when the joint main body 2 is pushed into the joint groove 1. The sealing material 4 is allowed to overflow from the location 3 to the outside through the overflow channel 5, and the joint body 2 is elastically deformed to ensure good watertightness in the joint body 2 itself. This is to ensure good watertightness.

[Example 1 Embodiments of the present invention will be described in detail below based on the drawings.

The watertight joint material A is extruded from flexible rubber or rubber-like elastic material, and specifically, as shown in FIG. The shaped portion 7 is made of rubber or a rubber-like elastic body and is made of the same color as the outer wall. Elastic fin pieces 8, 8 extend left and right behind the fin-shaped part 7, and further behind the elastic fin pieces 8.8, a sealing material holding part 13 having a substantially C-shaped cross section is provided with a rubber or Made of rubber-like elastic material in black color. The fin-shaped portion 7, the elastic fin piece 8, and the first sealing material holding portion 13 are integrally formed by extrusion molding. The interior of the sealing material holding portion 13 is a recess 3. I! One location 3 is filled with a paste-like sealing material 4 whose main component is unvulcanized butyl rubber or the like. The sealing material 4 filled in the recess 3 does not flow out in a natural state. A notch 9 is formed along the entire length at the base of the elastic fin piece 8, and a notch 9 is formed along the entire length of the elastic fin piece 8, and a notch 9 is formed in the middle part of the sealing material holding part 13. A notch 11 is also formed over the entire length of the notch 11 so that elastic deformation of the sealing material holding portion 13 can be stably performed in the notch 11.

However, this can be eliminated by adjusting the shape and wall thickness.

Therefore, the recess 3 is filled with the sealing material 4 in advance, and the filling operation of filling the joint groove 1 with the sealing material 4 at the construction site is omitted, thereby avoiding troubles due to insufficient filling of the sealing material 4. An overflow path 5 is formed in which the sealing material 4 overflows from the recess 3 to the outside, and when the joint main body 2 is pushed into the joint groove 1, the overflow path 5 is formed from the recess 3 due to the elastic deformation of the horse mackerel.
The sealing material 4 is allowed to overflow to the outside through the sealing material 4 to achieve a good seal. In this case, the overflowing sealing material 4 is prevented from leaking to the surface side of the joint main body 2 by the double blocking action of the elastic fin piece 8 and the surface fin-like part 7, and the appearance is kept good. be. A fin-like WS like this? By elastically deforming the elastic fin pieces 8, good watertightness can be achieved with the overflowing sealant 4 while also ensuring good watertightness in the joint body 2 itself.

In the figure, reference numeral 12 denotes a frame member, which supports the outer wall 6.

[Effects of the Invention] In summary, the present invention forms a recess at the back of a joint main body that can be elastically deformed, and fills and retains a sealing material that does not flow out in a natural state where no external force is applied to the recess. Therefore, the sealing material is filled in the recesses in advance, and the filling work of filling the sealing material into the joint groove at the construction site is omitted, and troubles caused by incomplete filling of the sealing material are avoided, while elastic deformation due to external force is avoided. Since an overflow path is formed in the recess to allow the sealing material to overflow from the recess to the outside, when the joint body is pushed into the joint groove, it will be lightly elastically deformed and flow from the recess to the outside. The sealing material overflows into the joint body and elastically deforms it, creating good watertightness in the joint itself.The sealing material also follows large irregularities on the sidewalls of the joint groove to ensure good watertightness. It has the advantage of being obtainable.
